Have you recently had a new furnace put in and are now experiencing a weird smell? You're not alone, because a lot of other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can anticipate it to go away, as well as three other furnace smells you shouldn’t disregard.
Why Your New Furnace Smells
There are two reasons why a new furnace might stink.
Protective Coating
Your furnace has a special coating on certain parts to keep them from rusting. This may include the heat exchanger, which safely gets rid of gases such as carbon monoxide naturally created during the heating process.
When your furnace runs for the first couple of times, the coating may emit a burning smell. This is normal and the smell should go away the more your furnace runs.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell continues. A burning smell that lingers can mean the motor has overheated or there’s an electrical problem, among other concerns.
Dust
Dust accumulates inside your furnace when it’s not running in the spring and summer. That dust will burn off when you turn on your furnace in the fall, creating a burning smell. This smell should go away within a few minutes.
One way you can lessen or prevent this smell is by having furnace maintenance done each year. This is necessary to keep your valuable manufacturer’s warranty valid, plus it keeps your furnace clean and ensures it will run properly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Ignore
While it’s less common for a new system to need furnace repair, it can happen. Here are three other smells you should watch for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical issue. Electrical wiring is covered in plastic to prevent shocks, and this smell is an indication that heat is melting this protective coating. To avoid a fire, turn off your furnace immediately and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies include sulfur in natural gas to alert you when there’s a problem. If your furnace smells like gas or rotten eggs, shut it off right away, leave your home and call 911. Exposure to natural gas can make you sick, plus it’s extremely flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We recommend having your ductwork checked and cleaned if needed.
